Rubber, natural latex concentrate - Determination of KOH number (ISO 127:1995 + Amd. 1:2006);English version of DIN ISO 127:2008-06

DIN ISO 127-2008 发布历史

This International Standard specifies a method for the determination of the KOH number of natural rubber latex concentrate which is preserved wholly or in part with ammonia. The method is applicable to latices containing boric acid. The method is not applicable to latices preserved with potassium hydroxide. It is not necessarily suitable for latices from natural sources other than Hevea brasiliensis, or for latices of syn- thetic rubber, compounded latex, vulcanized latex or artificial dispersions of rubber.
